afks and the ranked community

the fact that i lost my promos from a afk'er is stupid. honestly there should be a system in place for players that protects us from afk'ers. something that prevents LP lose and promo loses if your team has an afk. we shouldnt have to post on the forums beggin for justice. we should have justice right away. it is after the fields of justice. so where is ours? i have spent over 500$ dollars on this game and will continue to spend more..but honestly you may lose me as a player and customer riot because of this. and yes i know im in bronze. plz riot. PLEASE!
